What is a common characteristic of dairy cows that makes them easier to handle?

Dairy cows are generally breed and raised to be more docile and accustomed to human interaction than some other livestock. This characteristic makes them easier to handle, as they tend to be less skittish and more predictable in their behavior. Farmers often have daily interactions with dairy cows for milking, feeding, and care, which helps to socialize them and reduces fear of humans. Their temperament is essential for safety in handling practices, ensuring both the well-being of the animal and the safety of the handlers.

The other options do not accurately reflect the primary reason dairy cows are easier to manage. While size may play a role in handling ease, it is not the defining characteristic when comparing dairy cows to other types of livestock. Similarly, a lower feed requirement or increased agility does not specifically contribute to their ease of handling relative to their temperament and familiarity with humans.
